SUMMARY

In the scholarship on the concept of political corruption, one frequently encounters the lamentation that the manner in which the concept is deployed in liberal modernity is insufficiently attuned to the richer sense in which the term was employed in the ‘civic humanist’ tradition. In these lamentations, the usual point of reference is J.G.A. Pocock's The Machiavellian Moment, a work that made corruption the central term of art in a political language stretching from the Renaissance to the eighteenth century and beyond. Certainly there is something quite attractive today about the ‘Machiavellian’ inflection of the term—our era is replete with the very things the protagonists of Pocock's story decried: debt, dependency, oligarchy, standing armies and the diminution of civic duties. But to what extent is Pocock's classic text a reliable guide for those studying the concept of corruption? This article suggests that Pocock uses the term in an excessively capacious manner, which both weakens his book's utility for understanding eighteenth-century political thought and undermines its power as a foundation for political critique by civic-minded anti-corruption reformers.  相似文献

This is the second in a series of Viewpoints about a symposium on the intersections and antagonisms between various forms of feminism and the politics of childhood. This article traces the various ways in which time and temporality were mobilised in symposium papers and discussions and considers the implications for efforts to conceptualise woman–child relations. In conclusion, the potentials and risks of focusing on temporality when theorising relations between those positioned as women and those positioned as children are considered.  相似文献

东汉后期著名史学家荀悦的著作《汉纪》和《申鉴》中包含着卓越的史识。这主要表现他把历史看成是发展的,各种制度应适应时代与社会的发展而变化,统治者必须随时而变,随机应变。他认为考察历史问题应与具体的社会环境结合起来,具体问题具体分析,主张将不同的政治主张置于具体历史时空中探讨。他既能从整体上把握事物,从多角度加以探讨,又能考察事物的不同方面,分析其内在联系。他看到事物具有相对性的特点,主张通过比较把握事物的共性与个性,认为考察事物要透过现象看本质。他朦胧地意识到事物内部存在既相互对立又相互联系的两个方面,在人物评价中注意分析其两重性。荀悦的史识值得我们认真总结。  相似文献

In this review essay, I examine the arguments made by Marnie Hughes-Warrington, with Anne Martin, in Big and Little Histories: Sizing Up Ethics in Historiography. While I find much to praise in this history, I also ask critical questions about the impact of non-Western ethics on historical writing, the role of ethics in historical writing generally, the need to further investigate the everyday lifeworlds of history makers in order to fully understand their ethical dispositions, and the relationship between the ethics of history making and engaged forms of historical writing. I conclude this review essay by offering some reflections on the interrelationship between history and memory and the ethics involved in both.  相似文献

One of the main debates regarding historical representation within digital media concerns narrative, particularly the difficulty in articulating it. Digital technologies are usually presented as opposed to linear, written narratives, which is of consequence to historical writing. Despite the many merits of scholarly approaches that try to circumvent this difficulty, the lack of theoretical understanding of the categories implied in such discussions is noticeable. To counter this, this article addresses the relationship between time, technics, and narrative. I contend that the challenges of crafting narratives in digital media conceal a problem pertaining to the relationship between time and technics. Drawing on Paul Ricoeur's work on narrative, Jimena Canales's studies of the history of science, Wolfgang Ernst's and Yuk Hui's discussions of technical temporality, and Bernard Stiegler's understanding of the relationship between time and technics, I argue that it is the temporality imbued in the workings of technical objects (such as computers) that renders them averse to narrative. In making this argument, I employ the notion of “counted time” (in contrast to Ricoeur's “narrative time”) to denote a temporal mode that, despite its intersections with social, human temporality, is alien to narrative.  相似文献

A major advantage of satellite remote sensing is that the imagery acquired provides a synoptic view of the landscape. Thus, repeat coverage by the satellite on a regular basis permits the detection of changes in land‐cover over time. This study demonstrates the application of remote sensing technology to the monitoring of mining activities at the Athabasca Oil Sands region of Alberta, Canada. First, we describe the techniques used to match a time sequence of Landsat imagery, both spatially and spectrally, to ensure that the spectral changes through time are due to land‐cover variations. A series of spectral trajectories were then extracted to assess changes in land‐cover through time. Secondly, a land‐cover classification was produced from the baseline 1984 imagery and, using historic and future mine extents, the classification was analyzed to determine the proportion of each land‐cover type affected through development. Results of the analysis indicate that since 1984 there has been a larger reduction in mixedwood dense and broadleaf vegetation classes than mixedwood sparse or dense conifer stands in the area. Based on the delineations of mine‐site activity, the area of woodland and wetland habitat subject to development has increased from approximately 2,520 hectare (ha) in 1984 to 32,930 ha in 2005.  相似文献

This paper presents the results of a comprehensive comparison study between the analytically predicted and experimentally identified dynamics of the shaking table system built recently in the Structural Engineering Laboratory at Rice University in Houston, Texas. The primary objectives of the research presented here are two-fold: (1) to shed light into the dynamic performance of asmall-tc-medium size, uni-axial, servo-hydraulic, displacement-controlled shaking table system, and (2) to validate a linearised dynamic model of the system (in the form of the total shaking table transfer function) developed earlier by the authors from basic principles. The analytical model incorporates the inherent dynamic characteristics of the various components of the shaking table system (i.e. controller, servovalve, actuator, test specimen, and reaction mass) and their dynamic interaction.

The test-analysis correlation study performed over a wide range of operating and payload conditions provides useful information on the sensitivity of the shaking table transfer function to control gain parameters and how it can be used to tune the shaking table controller for optimum performance under various payload conditions. The good test-analysis correlation results obtained validate the analytical shaking table model, show its robustness, and provide keen insight into the underlying coupled dynamics of a shaking table system. In order to achieve this good test-analysis correlation, it was crucial to include a time delay in the analytical model of the shaking table system (innovative feature of the model to account for the time lag in the response of the servovalve-actuator system). The expected significant dynamic interaction between payload and shaking table is also confirmed by this study.  相似文献

Wetlands are common in Coastal Western Hemlock forests yet the hydrologic processes that generate runoff from small swamps are not completely understood. Direct field observations, hydrologic, and electrical conductivity data were collected from a gently sloping forested swamp complex from July to November 2009. Swamps occupied depressions between raised mounds (0.1 to 3 m high) and were connected by an ephemeral creek. Runoff was controlled by antecedent moisture conditions and influenced by basin microtopography. Two hydrologic regimes occurred during the study period and different runoff processes dominated each regime. Runoff was generated by subsurface flow during dry antecedent conditions as swamps remained hydrologically disconnected from each other. Runoff was generated by surface outflow from hydrologically connected swamps during wet antecedent conditions as ponded water spilled out of the depressions. The forested swamp complex produced a faster but limited hydrologic response during dry antecedent conditions compared to a slower but greater hydrologic response during wet antecedent conditions. Stormwater runoff and runoff ratios were up to two orders of magnitude higher in wet conditions than during similarly sized events in dry conditions. These factors should be considered when designing monitoring programs or runoff models in forested swamps with significant microtopography. Field surveys and estimates of hydrologic inputs and outputs may be useful in predicting the potential hydrologic connectivity of isolated forested swamps.  相似文献

Few previous studies of socio‐spatial isolation have explored both its spatial and temporal dimensions. This study proposes and implemented four visual methods for analysing socio‐spatial isolation using graphic representation of people's social networks and activity patterns in space and time: 3D space‐time paths, time windows, 3D activity density surfaces, and ring‐based visualisation of social networks. These visualisations utilise both activity‐travel data and social network information. The data used were collected through a specially designed activity‐travel diary survey with a sample of Koreans in the Columbus metropolitan area in Ohio (USA). The results show that these visualisations can considerably enhance our understanding of the relationships between people's activities in space‐time and their social interactions. Combining social network analysis with activity pattern analysis can lead to a better understanding of socio‐spatial isolation.  相似文献

Tourism is one of the world's largest legal industries. At the same time that tourism has grown so has its study, to the extent that there is debate as to whether it may constitute a discipline in its own right. Geographers have long contributed to the study of tourism. However, there is substantial concern over the development of the sub‐discipline and how tourism is conceptualised. A framework for understanding tourism in relation to contemporary human mobility over space and time is provided. This framework bears strong relationships to research on time geography as well as to work on diaspora and transnationalism. Some of the implications of incorporating tourism within the framework of mobility are outlined with respect to mobility as a form of capital, the relationships between different forms of mobility, and an improved understanding of tourism's impacts at all stages of the travel process rather than just at the destination.  相似文献
